T11 fc/I Irl/..0111r it 11141.41/ calmer/b:

Be it known that l, GEORGE A. Omvnn, a citizen of the Unit-ed States,residing at Gardiner, in the county of Kcnnebec and State of Maine, haveinvented a new and useful Bal-A anced Compensating Pipe-Joint, of whichthe following is a speciication.

T his invention relates to slip-joints for use 'in connection withsteam-pipes and its object is to provide a joint of this character forconnecting two pipes extending at angles to each other so they cannotbecome detached through expansion or contraction of the pipes and whichdoes not necessitate anchoring in order to hold the pipes in properrelation to each other.

The invention consists of a sleeve to which one of the steam-pipes isadapted to be connected, and extending through the sleeve is alongitudinally-slotted pipe one end of which is closed. The entireinterior of the sleeve is of greater diameter. than the exterior of theslotted pipe, and therefore a compartment is formed around the slottedpipe 'to facilitate the passage of steam from one of the pipes to theother. Packing-glands are located in the ends of the sleeve to preventleakage of steam.

The invention also consists of certain other novel features ofconstruction and combinations of parts which are to be hereinafter morefully described, and pointed out in the claim.

In the accompanying drawings is shown the preferred form of theinvention.`

In said drawings, Figure 1 is a side elevation of the joint, and Fig. 2is a longitudinal section therethrough.

Referring to lthe figures by numerals of reference, 1 is a substantiallycylindrical sleeve with a collar 2 at each end anda tubular stem 3,which projects from the sleeve at a point between its ends andisthreaded to engage a steam-pipe 4. A gland 5 is arranged at each endof the-sleeve l, and bolts 6 extend through the collars 2 and the glands5 for the purpose of tightening the lands to render them steam-proof.The g ands coperate with interior flanges 7, which are cast within thesleeve and form a steam-compartment 8 therebetween. A steam pipe 9extends through the glands and the flanges 7, and lonf gitudinal slots1() are formed in that portion of the pipe located within thecompartment 8. A collar 11 is formed on the pipe 9 adjacent one of theglands, and the end of the pipe is closed and projects into the recessedface l2 of a head 13 in the form of a ring, adapt-ed to be secured tothe end of the pipe 9 by means of screws 14 or in any other preferredmanner. It will be obvious that with this ,construction when steamenters pipe 9 it will escape through the slot-s 9 into the compartmentb. It will then flow outward into pipe 4,; The passage of steam throughthe pipe will capse more or less expansion and subsequent contractionthereof, and this is allowed by reason of the fact that the pipe 9extends through the sleeve 1v and is capable of longitudinal movementtherein. 'I his movement will be limited by head 13 and collar 11, andthe slots 10 will at no time be removed from the compartmett S. Withthis construction there is no danger of the two pipes becoming separatedbecause of any expansion or contraction thereof, and steam is at alltimes free to pass from one pipe to the other. As the sleeve 1 embracespipe l) at opposite sides of the slots 10, the joint becomes perfectlybalanced and does not require any anchoring means for holding the twoparts in proper relation. i v

I claim- The combination with a sleeve'having interior annular liangesbetween the ends thereof and forming a stealn-compartmcnt, and an outletfrom said compartment 4 of glands in the ends of the sleeve andconnected thereto,

a pipe slidably mounted within the glands' and surrounded by theinterior flanges, said pipe being closed at one end and extendingthrough the center of the steain-compartment, a stop-ring detachablysecured upon and extending beyond the closed end of the pipe, and anannular collar integral with the pipe, the sleevemandN glands beinginterposed between the collar and the stop-ring to limit the'independent movement of the pipe, said pipe havingahpiliirality'of'lengitudinal slots for directing steam into allportions of the steamcompartment.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
